Description
Westcoat MACoat Under Tile System is a waterproof
reinforced deck system installed with a series of two
separate waterproof applications, The first layer is WP41 Sheet Membrane, a 60 mil rubberized asphalt selfsealing membrane. The second layer is a highly resonated
cement designed for extra waterproofing and to protect
the sheet membrane.

Preparation
Inspection
Prepare surface by brooming, vacuuming, high-pressure
clean, dry air, or grinding to achieve a clean, dry surface.
Be sure the surface is clean, dry and free of grease, paint,
oil, dust or any foreign material that may prevent proper
adhesion.
Concrete should be a minimum 2,500 psi and must have
¼ inch slope per lineal foot with a smooth finish and be
open and porous. Allow concrete to cure a minimum
28 days and make sure that the moisture content is at
4% or less. If doing a calcium chloride test, the reading
should be five pounds or less of vapor transmission per
1,000 square feet. Another test can be done by taping a
plastic mat or visqueen onto the surface, then waiting 24
hours before checking for moisture. Decks must be built
to meet local building code.
For rough concrete a slurry coat may be applied. Combine
1 bag of TC-1 Basecoat Cement with 1 gallon of WP-81
Cement Modifier and up to ½ gallon of water and trowel
smooth.
A P P L I C ATI O N
Concrete Seams and Cracks
Cracks greater than 1/32 inch should be routed out ¼ x ¼
inch. Install WP-47-3 Seam Tape over all cracks and seams.
Apply EC-72 Epoxy Patch Gel into the tape with a trowel
or putty knife to smooth. Allow EC-72 3-4 hours to cure
before the application of the WP-41. This is a remedial
Note: If the flashing is not bonderized it must be etched
or roughed up so that the coating will bond.
Primer Requirements
Priming is required over properly prepared concrete.
Apply the WP-43-H Sheet Membrane Primer to the
concrete at a rate 150 to 250 square feet per gallon. Do
not allow primer to puddle, or have excessive amounts of
primer, this may cause blistering. Brush or roll out primer
being sure entire surface to be waterproofed is primed.
DO NOT COVER WET PRIMER. Prime only what you can
cover with the membrane in 4 hours. Apply membrane
when the primer is tacky but not wet. Primed areas not
covered in 8 hours must be re-primed.
approach to patch cracks and there is no guarantee that
cracks will not reappear.
Flashing
Flash at the junction of the wall and the deck using 6
inch x 4 inch flashing. Flash the fascia with 2 x 4 inch drip
edge flashing. Use a minimum of 26-gauge bonderized
sheet metal. Flashing should be set in a bed of EC-72
Crack Patch Gel and nailed only as needed. The vertical
portion of the wall to deck flashing should be nailed at all
studs, after the epoxy base has cured. Overlap all seams
at least 4 inches. Caulk between overlapped flashing as
well as the seam with WP-51 Polyurethane Sealant.
Sheet Membrane
1 of 2
Apply Sheet Membrane to the entire deck. Using a seam
roller, roll the deck to smooth out any bubbles.

Mastic Application
per batch. For easier application, you may add up to 1
quart of water to help loosen up the mix for easier
application.
Apply WP-42 Sheet Membrane Mastic to all terminating
edges, end laps and to any detailed areas. The mastic
should be applied the same day of the application.
Flood Test
MACoat Application
Prior to flood testing allow mastic 24 hours to fully
cure. Perform flood test with a minimum of 1 inch and a
maximum of 3 inches of water for 24 hours.
Drains should be plugged and barriers placed to contain
the water.
Mix at a 1 to 1 ratio (one bag TC-1 to 4 gallons of WP-90)
and trowel the entire surface smooth (as thin as possible)
or at the rate of approximately 300 to 350 square feet
Clean Up
Uncured acrylic material can be removed with soap and
warm water. If cured, material can only be removed
mechanically or with an environmentally-safe solvent.
H E A LT H P R E C A U T I O N S
Inhalation of vapor or mist can cause headache, nausea,
irritation of nose, throat, and lungs. Prolonged or repeated
skin contact can cause slight skin irritation.
Cements contain silicas, dust mask or respirator should be
used when mixing, sanding or grinding.
